I purchased my Slash VXL 2wd a little over a month ago and have been loving it ever since. Just the other day I took it out for a run and the motor had a high pitched whine much different from it's normal operating sound.I contacted Traxxas about the issue and had stated I was 5 days past the warranty period. They had me ship the motor in with the ESC. Within 2 hrs of receiving it they determined it was a defective motor and shipped a new replacment. That is what customer service is all about! Great job Traxxas!
